JAMES POLHEMUS VAN WYCK, OF HUDSON, NEWV YORK.

DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 414,093, dated October 29, 1889.

Application filed July 24, 1889- Serial No. 318,544:- (No model.)

To all whom it may concern.-

Be it known that 1, JAMES POLHEMUS VAN WVYCK, a citizen of the United States, and a resident of Hudson, in the county of Columbia and State of New York, have invented certain new and useful Improvements in Dumping- Wagons; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Figure 1 is a side view of my improved dumping-wagon, showing the wagon-box in its normal or lowered position. Fig. 2 is a similar view of the wagon, showing the box in its elevated position ready for dumping the load. Fig. 3 is a front view of the wagon with the box elevated as in Fig. Fig. a is a vertical transverse sectional view on line a: a; in Fig. 1, looking toward the back part of the wagon. Fig. 5 is a longitudinal sectional view of the friction-gear and shaft, &c., for elevating the wagon-box. Fig. 6 is a detail view of the worm-gear for revolving theshaft. Fig. 7 is a top or plan. view of the frame which supports the box, showing the operating-shaft and gears with their appurtenances; and Fig. Sis a detail view of the front braces.

Like letters of reference denote corresponding parts in all the figures.

This invention has relation to that class of dumping-wagons in which the wag'olrbox containing the load to be dumped is capable of being raised or elevated and then tilted to one end or side, so that its bottom will form an inclined plane at such an angle that the load or contents of the box will slide out upon removing the end-gate or one of the sides of the box, according to whether the wagon is designed to dump or discharge its load endwise or sidewise.

This class of dumping wagons as heretofore constructed has been operated by means of intermeshing cog-wheels and levers, the employment of which involves considerable friction and expenditure of power in order to elevate the box and its load and pitch it at the proper angle; and one of the objects of my invention is to simplify the construction of the elevating-gear, so that the same may be operated with a minimum of power, and also to so construct the various co-operating parts as to produce a dumping wagon which,'while comparatively simple and inexpensive in construction, shall yet be sufficiently strong and durable to Withstand rough usage.

Another object aimed at is to so construct the elevating-gear and its appurtenances that the same may be applied to wagons of the ordinary construction already in use, as well as to the box-cars or gravel-cars used in the construction of railways.

WVith these several objects in View my invention consists in the detailed construction and combination of parts of the dumping wagon, which will be hereinafter more fully described and claimed.

Reference being had to the accompanying four sheets of drawings, the letter A designates the running-gear, which may be of any desired construction. This running-gear supports the bottom frame B, comprising the parallel side sills O O and front piece D. Upon the side sills O are bolted--one on each side-the standards E E, the upper ends of which form bearings for the grooved sheaves or pulleys F.

The wagon-body G is provided on its under side with depending brackets or hangers H- one on each side of the shape shown in the drawings, and bent attheir lower ends to form hooks I, in which one end of the hoisting-chain (shown at J) is fastened. The other end of this chain (of which,of course, there is one on each side) passes over its appropriate grooved sheave F, down along its appropriate standard E, to and around its appropriate drumK on the hoisting-shaft L. The latter is journaled in boxes or bearings M upon the side sills O of the bottom frame, and is constructed as shown more clearly in the sectional View Fig. 5. From this it will be seen that one end of said shaft (marked L) is solid, while the other end is bored through centrally, so as to form a tube for theinsertion of the sliding rod N, the projecting outer end of which is provided with a handle 0. The, winding-drums K K are fastened by means of keys or other suitable devices upon opposite ends of the shaft L L, just inside of the side sills, as shown in the drawings, and are provided with screws or bolts P for the attachment of the lower ends of the hoisting-chains J.

By reference to Figs. 5and 6 it will be seen shaft, permitting it to-slideforwardand naci to the inner sides of one of the side sills O, as

will appear more clearly by reference to Figs. j

3 and '7 of the drawings. Thusit will be seen that when the Worm-shaft T is rotated it will revolve the intermeshin g cog-wheelQ, thereby revolving shaft L L, thus Winding the hoist-.

ing-chains J around tl1ei1'*approp1'iate dr'uins, and thereby elevating the wagonbox intothe dumping position illustrated in Fig. 2.

The box R, covering the worms audits in V terineshing gear-wheel or cog-wheelQ, is provided-on its open side with a cover R", within which is placed the beveled friction-wheel W, which is fastened upon shaft LL,-'so as to re- 2 volve with it, by means of a pin or key X,engaging a slot or recess in the -h'uio ot the wheel.

The latter has a central recess Y encircling the shaft L, and within this recess is placed a'coiled spring Z. The rod N works loosely in the central bore of the tubular part of and the key X is inserted through a slot at th inner end of said rod. Under normal conditions the coiled spring Z will operate to sepai rate the beveled friction-wheel W'from the; beveled friction cup or brake a, located within box R; but by pulling upon the projecting handle 0 'sprin g Z will be coinpressed:, so as to bring the beveled periphery of the frictionwheel W in frictional contact with the brake- 'cuipor frictionmup a, which position illn's- Another key b is inserted traced in 5. through a slot in rod N and through corresponding 'slots in shaft L, the slots in the "shaft being of sufficient length to allow the keysuffi'cient play forward and back to 'oiperate the friction-wheel W in the manner described, so that 'whiie irod N may be pulled forward or back to a limited extent, but su ffi- I cient to engage "or disengage the frictionwheel WV from its friction cup or brake a, yet i the centrally-sliding rod and the tubular;

box from being lowered too fast or too said; denly. By simply regulating the 'pullupon rod N the arnourrtof friction may be regulated'to a 1 nicety, so as to lower the box evenly and The Worm-shaftT is r journaled in brackets or bearings V V, affixed From the foregoing description, taken ing connection with Fig. 5, it will be seen-that? when the parts are in their normal condition "and the worm S is being revolved shafit L L I will also revolve, thereby revolw'ng the hois-ting d'ru ms K K and raising or lifting the smoothly without any sudden jar or concuss1on.

In order to guide the wagon-box While it is being raised or lowered, I provide the rear end of the bottom frame with curved guides c-one at each side-which are slotted to re ceive bolts d, 'affixe'd in the bottom of the wagon box or body and traveling in said slotted guides. The opposite or forward end of the Wagon-box is provided with jointed braces e, the lower ends of which are pivoted upon bolts f in the forward ends of the side sills. These jointed braces e are so constructed that they can be doubled in one direction only-- via, inwardly toward the rear end of the 3 wagonone of the jointed parts being provided with projecting shoulder g, bearing a ainst a corresponding recess h in the oppoe part in substantially the 'saineinanneras dl and from thisconstru'ction it follows that tire two parts of the jointed braces can be folded or doubled upon each other in lowering the wagon-box only in the direction of the rear end of the wagon, as indicated by dotted lines in Fig. 2. From this construction it results that after the hoisting-drums have been revolved until the hoisting-chains J shall have elevated the wagon box into the 1 position :shown in Fig. 2 the box wiil of itself resume the i'earwardly-inclinedposition illustrated in this figure, thecenter of gravity being toward the rear side 0f the brackets or hangers H, to the hoisting-chainsare attached, these hangers or brackets permitting the bottom of the box to be raised or lifted "entirely clear of the upper ends of the standards E, so that the box will readily tip itseitfinto the inclined position shown in the drawings, sothatby removing the end-gate the load will be dnrnped. After this has been accomplished the wagon-box is again lowered into its normal position simply by pulling upon the handle Onntil sufficient friction has been attained to enable the box to lower itself easily and gradually, the jointed braces at the same time folding inwardly and doublingnpon themselves, while du-rin g the lower- I ing of the box the same is maintain-ed in its E proper position by means of the slotted guide-so.

if it is desired to dump the load sidewise insteadof endwise, the hoisting and lowering mechanism is simply located nponthe bottom frame at right anglesto the positionshown in the drawings, when it follows that the wagonbox will be tilted =or inclined in a sid'ewise direction instead of endwise. The latter'construct ion may be employed to advantage on railway-cats er gravel-cars for duinping ballast or gravel u pon railways during the construction or repairing of the same, and by elevating and tilting the wagon-box gradually the load may be dumped or discharged in installments, 'or little by little, as required.

From the foregoing it will be seen 'thatthe construction of my elevating and lowering IIO.

apparatusis of such a nature that it involves but few parts, and that these may be applied to any wagon of ordinary construction simply by providing the running-gear with a rectangular bottom frame or support. The whole apparatus may therefore be manufactured and supplied to the trade, the solid part of the shaft L L being made of suflicient length to be used on Wagons having comparatively Wide beds. In order to properly adjust the shaft to a narrower bed, all that is necessary is to cut oif a suflicient portion of the slotted end of the shaft to answer the purpose and adjust the position of the hoisting-drum K upon the shortened end of the shaft accordingly.

If desired, the entire operating-gear may be covered by a hood or casing of sheet metal for the purpose of keeping out coal-dust or dirt, 850.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States The combination of the bed or bottom frame having side standards E and bearings or boxes for the revolving shaft L L, the hoist ing-shaft L L, constructed as described, and provided with hoisting-drums K K, the hoisting-chains J, the movable Wagon boX or body provided With the hangers H, the curved end guides 0, adapted to engage guide-bolts projecting from opposite sides of the wagon box or body, and the forward jointed braces c, all constructed and combined to operate substantially in the manner and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
